I need you help to confirm or not theses notions plz. I'm trying to extract some TCP.analysis fields using python and for that I need to understant every field:

The next expected sequence number = ['TCP'].seq + len(['TCP'].payload)
The current sequence number =  ['TCP'].seq
The last-seen acknowledgment number = ['TCP'].ack

Thanks in advance for your help
